Question about the good old days

So is there really a lot more editorial control of comic book content now than there was in the old days (60s-80s)? I know there are more company-wide events now that require books to be more or less on the same page, but I think there's also now more of a notion that comics can be a creative medium in the same sense as novels or movies, that there can be a dominant creative voice. So there may be more of an expectation that that sort of creative control is an option, and perhaps it's more apparent when that's not there?
